First long game with advices from some friend with the Ottomans (5.1, no mods, DW installed):
PU with Tripoli and Nijni-Novgorod but never inherited, Austria never attacked me so I never attacked them ( :P ) and wanted to see some of "Ottoman South America" so I attacked and annexed Incas.
Early game I managed to get a PU with Mughals (after Timurids massacred Mamluks they formed Mughals, so when they didn't had their horde bonus and low legitimacy I rushed and forced PU) and after a few years I inherited lots of provinces, at least half of them with core, so it was easy after that. Got colonists idea for colonizing hordes and Africa.
P.S: Try to answer what nation is holding some provinces in eastern Spain (left of Aragon)
P.S2: At the 1800's, only for teh lulz, I massacred "le Blob" to see less blue in Europe :P
P.S3: USA, La Plata, Chile and Brazil are in their rightfully historical places xD And Aaschen is fine too (that purple thing in the middle of Europe)
